PaidLaunchVersion 1.0.0

Spec and for-sale checks, a reproducible ZIP proven to install in Claude Code, Codex and Cursor, and a Creem store where each buyer gets a licensed download and an install prompt, revoked on refund.

Full description

Turns a user's own Agent Skill into something people can buy and install. Checks the folder against the Agent Skills spec and for sale (name equals folder, description with a "when to use", metadata.version, license, no keys or home paths, script exec bits), builds a reproducible ZIP with a SHA-256 and manifest, and proves it installs for Claude Code, Codex and Cursor. Then sells it through Creem, either the no-code File Downloads add-on, or the Next.js template where the webhook grants a license per order, buyers get a 10-minute download link and an install prompt for their agent, each ZIP carries the buyer's license, and a refund or dispute revokes access. Ships /install/agent.md, 17 offline tests, a route test suite and an example skill. Use when the user wants to sell, package, license or publish a skill, a SKILL.md, a Claude Code / Codex / Cursor skill or prompt pack, or asks how buyers install a paid skill.

A sample store in Creem test mode selling the example changelog-writer skill for $19: the seller checks and packages it, a buyer pays with the test card, their agent downloads a copy licensed to them, and a refund through the Creem CLI shuts the link. · Recorded 2026-11-03

  1. 1The seller checks changelog-writer, packages version 1.2.0, and proves the ZIP installs for Claude Code, Codex and Cursor
  2. 2A buyer opens the product page and pays $19 in the Creem test checkout; the success page shows the download and a prompt for their agent (sped up 1.5x)
  3. 3The agent fetches the signed link and unzips into ~/.claude/skills; LICENSE.txt and whose_copy.mjs show the buyer and license id
  4. 4The order is refunded with the Creem CLI; the refund webhook revokes the license and the same link now answers 403

What it does

Spec and for-sale checks, a reproducible ZIP proven to install in Claude Code, Codex and Cursor, and a Creem store where each buyer gets a licensed download and an install prompt, revoked on refund.

  • check_skill.mjs runs the Agent Skills spec rules plus for-sale checks: name equals folder, a description that says when to use it, metadata.version, a license line, no API keys or home-folder paths, a #! line and exec bit on scripts
  • package_skill.mjs builds a byte-for-byte reproducible ZIP with the folder inside, a SHA-256 and a per-file manifest; test_install.mjs unpacks it into a clean home for Claude Code, Codex and Cursor and checks each one
  • Two ways to sell with Creem: the no-code File Downloads add-on for a first sale, or a Next.js App Router store with a product page, checkout, webhook and success page
  • The webhook grants one license per order and skill (packs grant several); a full refund, a dispute or an expired subscription revokes it, and each event is applied once
  • Buyers get a download link that lasts 10 minutes and a prompt to paste into their agent; every ZIP carries LICENSE.txt and a note in SKILL.md with the buyer's email and license id, and whose_copy.mjs reads it back
  • Ships /install/agent.md for agents, 17 offline tests, 5 route tests of the template, an example skill and reference notes on the spec, Creem, licenses and the product page
Try it with this prompt
Use the sell-your-agent-skill skill to check my skill in ./skills/my-skill, package it, and set up a Creem test-mode store on my Next.js site where buyers get a licensed download and an install prompt for their agent.
